I transformed my backyard and saved $10,000 in just two days. We built this DIY water feature start to finish with a Koi pond and waterfall in one weekend. This backyard transformation first began with a smokeless fire pit, a stamped concrete patio, an outdoor kitchen, a flagstone path, and a secret outdoor theater were built. We built this pond using a pond kit we purchased from ?@TEAMAquascape?. Now, we have a tranquil water feature we can enjoy from inside and outside.
